P/C> Blizzard Mastery Book

I acquired a Mastery Book for an I/L mage, the Blizzard one, and can't find a general price for it on Basilmarket or anywhere else. I want to sell it. Anyone have an idea on what it could retail for? I'm in Bera. Thanks very much.

I can't help, but it might help others to know what level the book is (20 or 30).
